Hello r-devel,
I have data.frame with 3 columns and I would like to group by 1 column(id),
find the max of the third column (date) and return the data for that max
date value along with the id and the value in the second column.
Example:
>dat <- data.frame(id = rep(1:3, 3), date = as.Date(rep(c("2

Bill,
This code has been touched by Brian quite recently. Try again with a
current r-devel checkout. (Specifically, l
Should the deparse.level=2 argument to cbind
and rbind be abandoned? It is minimally documented,
not used in any CRAN package, and causes some problems.
E.g.,
(a) If a matrix input has row names but not column names
cbind(deparse.level=2,...) stops.

This is really a question for R-help: it is not about R development
nor software development in R.
The answer to the only question I see is simple: your model depends on

Hello,
In the following I tried 3 versions of an example in R help. Only the two
first predict command work.
After :
library(splines)
require(stats)
1)
fm1 <- lm(weight ~ bs(height, df = 5), data = women)
ht1 <- seq(57, 73, len = 200)
ph1 <- predict(fm1, data.frame(height=ht1)) # OK
plot(wom
